Description
Technical field
The present invention relates to a kind of gaseous discharge lamp, relate in particular to incandescent light color electricity-saving lamp of a kind of high color rendering index (CRI) and preparation method thereof, belong to gas discharge tube technical field in the electricity.
Background technology
20 century 70s, the researcher just finds, the visible radiation that fluorescent material sends is positioned on several special narrow emission bands, by the wavelength (450nm, 550nm and 610nm) of suitable selection emission band and the ratio between these emission band intensity, suitably choose again fluorescent material, just can obtain the fluorescent material that existing high luminous efficiency has again extraordinary color developing.
The fluorescent lamp of making owing to calcium halophosphate activated by antimony andmanganese in the prior art, its spectrum red radiation is not enough, and the bluish violet radiation is superfluous, and color rendering index Ra is 60～70, and light decay is large, and lux maintenance is low.Therefore be not suitable for and be used in the fine-pipe-diameter energy-saving lamp.
By fluorescent material: BaMg
2Al
16O
27: Eu (blue powder of λ master=450nm), CeMgAl
11O
19: Tb (the green powder of λ master=545nm) and Y
2O
3: three narrow bands of a spectrum of Eu (rouge and powder of λ master=611nm) according to a certain percentage, the straight type fluorescent lamp Ra that makes the different-colour of 2300-8000K can reach 85, and very high light efficiency is arranged.By the various compact type energy-saving lamps that above-mentioned three kinds of fluorescent material are made, color rendering index Ra generally can reach about 80, but is difficult to be improved again.The reason that produces the problems referred to above is owing to the bluish-green powder of 480～520nm in the spectrum of the tricolor powder of above-mentioned three kinds of fluorescent material composition and inadequate greater than the rouge and powder of 620nm.
In order to improve the color rendering of electricity-saving lamp, released again BaMgAl on the market
10O
17: Eu, this fluorescent material of Mn, it has the Eu2+ radiation of λ master=450nm, and can produce simultaneously λ master=515nmMn2+ radiation, the doublet blue powder in namely being commonly called as is by the concentration of Eu and Mn in the control molecular composition, can improve the color rendering index of various electricity-saving lamps, but the raising of color rendering index still is very small, and this doublet blue powder is mainly used in improving the color rendering of high color temperature electricity-saving lamp, can't well improve the color rendering of low colour temperature electricity-saving lamp.
Chinese patent application CN200710036123.0 discloses a kind of rare earth aluminate cyan fluorescent powder used for high color rendering property energy-saving lamp, it is mainly used in high color temperature (on the fluorescent lamp of the high color rendering index (CRI) of colour temperature＞4000K), make the fluorescent lamp of 2700K colour temperature with it, its color rendering index also can't reach 86.
The three primary colors fluorescent powder that is mixed with rouge and powder and green powder or the three primary colors fluorescent powder of rouge and powder, green powder and a small amount of blue powder have been adopted in the existing ordinary incandescent lamp look electricity-saving lamp, because fluorescent material lacks or deficiency at the emission spectrum of blue light region, so that the color of photographed object is fresh and alive not, if add a certain amount of blue powder to replenish the emission spectrum energy of blue light region in fluorescent material, the problems referred to above can solve smoothly.
This disclosure of the invention the incandescent light color electricity-saving lamp of high color rendering index (CRI) made of the multiple phosphor mixture of special proportioning and preparation method thereof, this electricity-saving lamp not only can satisfy the needs of low colour temperature 2700k, and color rendering index Ra is reached more than 86.
The consumer relatively favors in using warm-toned incandescent light color electricity-saving lamp in the modern house illumination, this just requires will accurately control the addition of blue powder on the ratio of phosphor mixture, because adding the excessive colour temperature of electricity-saving lamp that will cause, blue powder raises, colour temperature raises and will cause the tone of electricity-saving lamp to change cool tone into by warm tones, and then affects the market share.
